DECK DUMPING-SCOW.

SPECIFICATION formingpart of Letters Patent No. 273,178, dated February 27, 1883.

Application filed June 14, 1882. (No model.)

To all whom it may concern:

Be itknown that I, GEORGE SOUTHER, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvementsin Deck Dum ping-Scows; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

This invention relates to improvements in deck dum pin g-scows; and it consists of a deckscow having wheels or rollers located in bearings secured to the top of the deck, on which one or more dump-cars are arranged to slide in such a manner as to tip over the edge of the scow to empty the contents thereof in shallow water and close up to or directly upon the bank or wharf that is being made, and thus to dispense with additional handling of the mud, as all that is necessary to do with my improved deckdumping-scow is to empty the mud from the dredging-machine directly into the sliding car or cars on top of the scow, after which the latter is floated to the desired place where it is desired to fill in or to build a wharf or seawall, which is done simply by sliding the car or cars so as to. tip partially over one side of the deck-scow, when the end of such car or cars is automatically opened, allowing the car to discharge its contents at the waters edge, directly upon or in proximity to the wharf or wall that is being made. The sliding car or cars are provided with suitable holding-chains to prevent their going entirely over the edge of the scow, and are also provided with suitable blocks, chains, or ropes, or equivalent devices, to haul such car or cars back again into a horizontal position on the rollers on the top of the deck-scow, whereit is secured in position by suitable fastening devices, when the scow may again be transported to the dredging-machine to have its sliding cars again filled, and so on.

The invention is carried out as follows, reference being had to the accompanying drawings, on which Figure 1 represents a side elevation of my improved deck dumping-scow, and Fig. 2 represents a cross-section on the line A B shown in Fig. 1.

Similar letters refer to similar parts wheremptied of its contents or returned to its normal position above the deck of the scow. To prevent the car while in the act of dumping from rolling overboard, I attach to its forward end a pair of chains, d d, as shown in Fig. 2, the inner end of each of which passes through a suitable deck-bushing, d, and is preferably provided at'its end with a yielding buffer, d, made of rubber or metal springs, to ease the shock of the car when the chains (1 d get taut. To the rear end of each car is further secured a pair of holding-chains, e e, the inner end of each passing through a suitable deck-bushing, e, and provided at its end with a bnfi'er, e,

made of rubber or metal springs, tohold the rear end of the carin proper dumping position while it is in the act of discharging its contents.

f represents a block secured to the rear end of each dumping-car, by means of which and suitable ropes, ff, the car is hauled back and secured in place on the deck-rollers b b after it has been discharged.

The forward end of each car a is provided I with an end door, g, provided in its upper end with angular projections g g, the rear ends of which are hinged to the top of the car, by which arrangement the car can be discharged with much greater ease and dispatch as compared with cars having ordinarily-hinged doors. Theenddoor, g,is automatically locked and unlocked by the tollowing'means, viz: to the outside of the door g is secured the downwardly-projecting latch g, which is adapted to lock with the hooked end h of the locking-lever h, which is hinged at h" beneath the car a, as shown, and provided with a rear-extending arm, h'. In dumping the car the lever extension 72/ comes in contact with the edge of the deck of the scow, causing the hook h to be disengaged from the latch g", when the end door is automatically swung to the open position shown in the left-hand side of Fig. 2. After the car is dumped, as it is swung back to its normal position, the latch 9 comes in contact with the hooked end h of the lever h, which it depresses and automatically looks with, as shown. The weight of the rear ex tension, h,- of the lever It causes the hook it to remain in a locked position in relation to the latch g until the car is again to be dumped and so on.

The end gate hereinbefore described is especially adapted to the scow herein illustrated,

since it enables the dirt to be delivered to make land close to the shore and above the water-level.

What I wish to secure by Letters Patent, and claim, is- I 1. In combination with the deck-scow a a, its deck-rollers b b, and one or more sliding cars, 0, one or more forward holding-chains, d,

with buffer (1, as and for the purpose setforth. 2. In combination with the deck-scow a a,

its deck-rollers b b, and one or more sliding cars, 0, one or more forward and rear holdingchaius, d and e, as set forth.

3. In combination with the deck-scow a a, its deck-rollers b b, and one or more sliding cars, a, one or more forward and rear holdingchains, d and e, with their respective buffers d and c, as set forth.

. 4. The combination,with the deckscow having deck-rollers, of the sliding car 0, provided GEORGE soUTHnR- Witnesses ALBAN ANDREN, HENRY CHADBOURN.
